PAPER BOX.

SPECIFICATION forming part of Letters Patent No. 306,172, dated October7, 1884-.

A plication filed August 16, 188-]. (No modeL'r To rtZZ whom it mayconcern.-

Be it known that I, EDWARD B. NIUNSON, a citizen of the United States,residing in the city of New Haven, county of New Haven, and State ofConnecticut, have invented certain new and useful Improvements in PaperBoxes, fully described and represented in the,

following specification and the accompanying drawings, forming a part ofthe same.

The improvements embraced in the present invention relate to that classof paper boxes now commonly known as boxes, and wherein the blank whichforms said box is cut in a single piece from paper, card-board, or othermaterial, so as to provide four sides and end-closing flaps, whereby thecontents of the box are held and suitably in closed.

The invention comprises a new structure of such boxes, the sameconsisting in forming the blank cut and creased to form body parts,bottom flaps, bottom with pocketforming tongue and locking tucking flap,top closing flaps and top or cover with a tucking tongue, whereby a boxis formed that may be cheaply made withv a strong and substantial endand bottom capacitated to brace and support the body walls, provide apocket for the reception of the locking tongue of the closing end, andmeans for locking and retaining the parts comprising both top and bottomin their closed condition, and thus effectually holding the contentswithin the box without danger of the box becoming unfastened.

In the drawings, Figure 1 illustrates the blank from which the box ismade. Fig. 2 is a perspective view illustrating the box in apartially-closed condition. Fig. 3 is a central vertical section of thebox when in a closed condition. Fig. 4 is a view of one of the ends ofthe box, showing the closing flaps in a closed condition with the tonguebroken away; and Fig. 5 shows the node of cutting out, whereby economyof material is accomplished.

In a practical embodiment of this invention a blank is cut, creased, orscored and incised, as seen in Fig. 1, whereby is provided the box sidesU N S O and body-lap M, bottom flaps, D G, bottom F, pocket forming flapH, and locking flap I, top flaps, A 0, top or cover B, and tuckingtongue E.

knockdown The creasing or scoring of-the blank to proseveral portions ofthe box are manipulated to form the box is made on the lines 4: 5, to

permit the sides ,N O to bend or fold up at right angles to the side S;the line 3, to permit the side U to bend at right angles to the side N,and line 2, to permit the body-lap M to bend or fold inwardly at rightangles to the side U; 011 the lines 9 11, to enable the bottom flaps, I)G, to bend or fold inwardly at right angles to said sides N O; on line10, to enable the bottom F to bend or fold up at right angles to. saidside S; on the line 13, to enable the pocket-forming tongue to bend orfold inwardly at right angles to said bottom F; on line 14, to enablethe locking flap I to bend at right angles to said tongue H; on thelines 6 S, to enable the top-closing flaps A G to bend or fold inwardlyat right angles to said sides N O; on the line '7, to enable the top oreoverB to bend or fold over at right angles to the side S, and on theline 12 to enable the tucking tongue E to bend or fold inwardly at rightangles to said top or cover B. The blank is also provided with theincisions 17 18, to separate or free the bottom-closing flaps D G fromthe bottom F, and with the incisions 15 16, to free the top-closingflaps A G from the top or cover 13. A blank thus provided with lines ofcreasings and incisions which permit the several portions thereof to bebent or folded up on each other may be produced by any of the well-knowndies, or it may be performed by hand, or by any other method, and thusthe blank may be converted into box form in the following manner Thesides N O are bent or folded up at right angles to the side S, the sideU is bent at right angles to the side N, so as to lie in the same planewith the side S, and the fastening-lap M is bent ori'olded inwardly atright angles to the side U, so as to lie within and against the bent-upside 0, and may then be secured to said side 0 by cement or othersecuring means, thus making a tubular structure formed by the sides U NS O, as seen in Fig. 4. To close the bottom the bottom flaps, D and G,are bent inwardly at right angles to the sides N O. The bottom F is thenbent or folded up at right angles to said side S over thesaid flaps 1)G, and the pocket-forming tongue 11 isbcnt at right angles to saidbottom F, and its end and locking flap I is tucked into the interior ofthe box between the side U and the foldedover bottom flaps, I) G, so asto lie against the side U with its tucking flap I projecting from thetop or opposite end of the box, as seen in Fig. 2. The top of the box isthen closed by bending or folding inwardly one of the top flaps, as A,at right angles to the side N. The locking llap of the tongue H, whichwas projected out of top in closing the bottom, is then bent or foldeddown at right angles to said tongue II, so as to lie upon said flap A,as seen in Fig. 2. The other top flap, U, is bent or folded inwardly atright angles to the side 0, so as to lap upon the locking flap I andover the flap A. The top B is bent or folded at right angles to the sideS over the i'laps A I O, and its tucking tongue E is bent or folded downat right angles to it, and is tucked within the side U and between itand the pockett'orming tongue H lying adjacent thereto, as clearly seenin Fig. 5. The flaps D G- and A 0 might be of such length as to meet ornearly meet in the center. The locking flap I of the bottom tuckingtongue is thus confined be tween the flaps A and O and re-ent'orced bythe top or cover B, from which it will be seen that any tendency of thebottom bulging out from the weight of the contents of the box will beresisted by a direct pull. upon the top ilap, A, and likewise any suchtendency on the part of the flap A to bulge out will be resisted by thebottom F and its flaps D G. This loeling flap I might. however, be bentor folded over the two top llaps, A 0, so as to lie be tween the flap 0and the top or cover B, and still perform the function of preventing thebottom and top from bulging out, and aid in giving the box greaterstrength when closed.

By confining the tucking tongue E of the cover in the pocket formed bythe tongue H and the side U any injury to the contents of the box byreason of said tongue E coming in contact therewith in closing the coveris avoided, and the tongue E is prevented from injury and defectiveoperation which would result from contact with hard materials packed inthe box. The strongest form of structure thus not only obtained, but thedisposition of the parts enables boxes to be produced with greateconomy, as the blanks are shaped so as to be lapped past each other, asin Fig. 5, and thus be cut from the stock with great eeonomy-th at is,with a minimu in waste of unused material.

\Vhat l claim is The herein-described box, the same consisting of thebody parts U N S 0, lap M, bottom flaps, D G, bottom F, pocket-formingtongue H, with locking tucking flap I,- top closing flaps A (l, and topor cover B, with tucking tongue E, the whole formed in a single piece,and folded substantially as described.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses.
